yeah i'm gonna keep collecting the WA set to get all of them (or at least until i get all the ones i want from WA) and then trade off my dupes for 1-4 villagers' cards i want.
I'm a broke college student and yet I have a dream of owning every card from every series... and if that's not tough enough, I'm only just starting to collect them so I still actually need a ton of series 1 and virtually every card from 2-4, and I don't own the Sanrio or any Welcome Amiibo cards.
With the few doubles I have now, I've traded them off, although I have three extra copies of 002 Tom Nook that I haven't been able to get rid of yet. I think I'll start selling them once I have a lot.
I have found trading a bit of a struggle, since I'm in Europe and there's not as many Europeans on the post office as there are Americans/Canadians. Reddit just didn't have a single EUR trader when I last looked, several were at least willing to ship global though. I wish more people would do global trading.
Anyway, finally managed to get rid of all my welcome amiibo doubles, had a massive amount. Having difficulty shifting my series 1's though. Most people have completed that series by now. Welcome amiibo cards are in high demand though, there shouldn't be too many problems with getting rid of them
